I own a RTI P3 performance, which is an amazing gun, incredibly easy to tune & accurate, so when all the hype about the Mora first started I already knew that was going to be my next purchase, a 700mm in .25 calibre.
The first Mora I received had a badly etched serial number, so I couldn't put it on my firearms certificate, back that went & then I had a very long wait to receive another one.
My new gun finally arrived on the 14th of February & was the new version with the pneumatic hammer system, I brought a series of slugs, ZAN 45grn, Zan 41grn, H&N 36grn, H&N 46grn & others. I was favouring the ZAN 45grn knowing that many of the YouTube guys & airgun forum members were having amazing success in their .25 700mm Mora's.

After a barrel clean I sat down at my bench to start zeroing & tuning, with an FX Ballistic chrono, no matter what I did, including following advice from many other shooters, the owners manual, etc & trying in vain to reach out to RTI themselves. I Could not get the gun to group. So I decided to borescope the barrel, the crown appeared very shallow & not what I would of expected from a LW barrel, also the rifling was badly cut & uneven.

So back to the distributors, Highland Outdoors & credit to them, they agreed with me on the barrel & swapped it out for a new one. I now have the gun back, accuracy is slightly better, but when I say slightly I mean golf ball sized groups at 50 yards, compared to tennis ball sized groups with the previous barrel. Also velocity was inconsistent, no matter what reg setting or valve setting.

So off I go to try to find & resolve the issue, things I tried include.

The obvious, multiple reg settings & valve settings.
Adjusted seating depth/head space.
Swapped optics.
Replaced slug probe oring.
Checked transfer port alignment.
Checked optics rail.
Re-indexed the barrel.
Borescoped barrel (crown is still shallow, but rifling is ok)
Used the bore scope to check for internal baffle strikes.
Weighed & sotted the slugs.
Checked over by my gunsmith (50 years of experience.
Got two others to shoot the gun.
Put the gun in a lead sled.

Believe me whatever your going to suggest ive tried it already 🤷🏽‍♂️

I fitted a digital gauge to the reg, to see if it was fluctuating (hard to tell sometimes with an analogue gauge), but its pretty consistent, although im having to run my reg at 170 bar, compared to others running 150bar to get the same velocity these guys were shooting the ZAN 45grn at 990/995fps.

My valve adjustment can be full closed or full open & anywhere between it has zero effect on speed, consistency, accuracy, etc, etc.

And believe me it's shot over a thousand slugs though it testing different combinations. And im no idiot when it comes to airgun tuning.

I did purchase this gun with the idea of getting into benchrest, but I have to say im very disappointed & disheartened with the gun & the whole experience. It pains me to write a negative piece on this, especially considering the huge success everyone else seems to be having. I guess I just got that one bad gun. I'm hoping RTI Arms / Rok may see this so the £2300 I've paid wasn't in vain & they step up as a reputable company & get this gun replaced.

It Amaze me the barrels LW will send out of the door, also amaze me the buyers of them have 0 entry check on them, or test of the final rifle.
But it is pretty normal from both AGT and FX i have bought the FAC rifles we Danes are still allowed to get, but in both cases gotten a SUB 12 rifle, and that is a very simple thing to make sure of you do not mess up.

So a lot of things are lacking in / from the enablers of our hobby, i for one often have the " not impressed " feeling also factoring in others experiences like here.

Also had to send back the LW barrel on my Two, the unchoked barrel was choked in the middle 25% of the barrel.
The replacement CZ barrel, slick as snot on a door knob and no sign of choke or loosening anywhere along the 700 mm

Totally understand FX changed to making their own barrels, even if you are still subject to the barrel lottery.

DrSeagram,
My deepest sympathies, I've learned the hard way, as well, regarding purchasing a new platform. My first "fresh-off-the-boat," airgun was a disaster, only paid $400, can't imagine your level of disappointment. Was also eyeing MORA in .357 but held off, so thankful I did. Hope RTI makes it right. WM

Version 1.uh-0 is why when the Prophet P2 was announced I bought one of the last Prophet Performance instead of jumping on the P2 beta tesing train.

I am interested in the Mora, but I never buy the first release of anything. I will wait until they are proven.
Good luck with yours DrSeagram. I am sure RTI will make it right.

I've got some questions on a few things you said. Please clarify if possible:

"My new gun finally arrived on the 14th of February & was the new version with the pneumatic hammer system,"
- What is the 'new' version? I got in early in the US with a 600mm Standard and while my valve does successfully modify fps - it is with a smaller range and the regulator setting does most of the power changes.

"I fitted a digital gauge to the reg, to see if it was fluctuating "
- How did you get the stock regulator gauge out? Which digital gauge did you get? It look like you can only fit a gauge which has a hex that comes all the way to the front readout - is there a tool or do you just use the right size socket?

The new Mora's don't have a hammer spring, the hammer now works on a pneumatic system. So you no longer adjust the hammer in the rear of the butt pad with an Allan key. It now self adjusts according to reg pressure. This cannot be retro fitted to the earlier Moras.

The gauge for the regulator can be removes by hand, fully degass the gun, the press gently on the guage & unscrew. I fitted a sekhmet 25mm digital guage in its place.

I know it seems crazy but have you tried to tune the gun down and shoot some pellets through it? To me it sounds like it can be not finding the right slug issue and not barrel necessarily. If you can see how it shoots heavy .25 pellets and it does good then you know you need to try different slugs.

I've tried over 4 brands & 8 different weights of slugs, I think thats enough, definitely enough on my wallet

Interesting - thanks for that information. Is this information actually available somewhere? I searched and I cannot find this change mentioned anywhere except in this thread.

That is correct. I cannot talk about the restrictions here due to obvious reasons... But I think it is clear anyway.

It's not my job as the end consumer to have to strip, modify & put right a gun that is brand new & purchased as FAC (full power).

This is not how the experience should be, tuning yes i totally understand that. But not hours, days, weeks of time & money trying to figure out why a new gun isn't performing as it should.

that should be directed at highland outdoors,they dont have a clue.
but on the other hand would you want them in there doing stuff:eek:

i have already said to rok he needs a better importer,they are the ones causing the problems.

i think they are now due us around 1500 slugs because of their fecklessness
